Hi
Is it a simple procedure for a judge to rescind an order he/she has just given? In the following case a judge had granted a man joint legal custody of a child born to a woman who had been (unbeknownst to the judge at the time of granting the order) accused of raping her when she was 12. If the judge decided on that basis to reverse the decision and rescind the order, is it a simple matter of voiding it or does it require another hearing/trial?

Michigan Supreme Court spokesman John Nevin told The Associated Press on Wednesday that Sanilac County Judge Gregory Ross didn’t know 27-year-old Christopher Mirasolo had two criminal sexual conduct convictions, including one concerning the woman. Nevin says the judge put the order on hold Tuesday after learning of Mirasolo’s criminal past.

It’s really easy. Procedures likely vary from state to state but generally a judge could do so either “sua sponte” (on the judge’s own initiative) or in response to a motion from one of the parties (like a motion to reconsider).

As long as the judge’s court still has jurisdiction, it should be straightforward (although family law is not my area). But there are events, like an appeal, that can divest the court of jurisdiction.
